| Abstract: | Technologies of vacuum pumping and maintaining of the field emission display (FED) devices were modified.The modification includes the novel design of the three plate FED package structure,inert gas protection during sealing,and usage of both volatile and non volatile gettering materials.Moreover,electron bombardment of the phosphor screen is introduced to effectively remove its adsorbed gases in the course of exhausting.Our results show that the new FED cathodes enjoy many strengths,such as better vacuum environment higher stability,and longer lifetime |
